Electrodes and Cells

Setup of the Electrochemical Cell

The setup of the electrochemical cell, including the various electrodes, cabling, shielding and the cell itself is critical to making precision measurements.  The notes below are useful references for checking and optimizing the setup at the end of the cable.  Click on a link below to view the Application or Technical Note.

Reference Electrodes

Posted on 2 August 2013

For reliable reference electrode performance, you should assign a “Lab Master” and treat it very, very carefully so it can serve as a standard for your other reference electrodes.

Measuring the Impedance of Your Reference Electrode

Posted on 2 August 2013

It's very important for optimum potentiostat performance that the impedance of the Reference Electrode in your cell is low!

Care of Vycor® Porous Glass Frits

Posted on 2 August 2013

Vycor® is often used at the end of a reference electrode or a bridge tube to allow electrical, ionic conductivity between the bulk of the solution and the internal filling solution, while preventing large scale convective mixing of the solutions. Vycor, or "thirsty glass" is a porous glass with a fairly low leak rate.

Two, Three and Four Electrode Experiments

Posted on 25 July 2013

Electrochemical experiments range from simple potentiostatic (chronoamperometry), to cyclic voltammetry (potentiodynamic), to complex AC techniques such as impedance spectroscopy.
